After a fuse is replaced

• If the lights do not turn on even after the fuse has been replaced, a bulb may need replacement.
• If the replaced fuse blows again, have the vehicle inspected by your Toyota dealer.

If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.

CAUTION

To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or injury.

• Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse.
• Always use a genuine Toyota fuse or equivalent.
  Never replace a fuse with a wire, even as a temporary fix.
• Do not modify the fuses or fuse boxes.

NOTICE

Before replacing fuses
Have the cause of electrical overload determined and repaired by your Toyota dealer as soon as possible.

How to Replace the Fuse of the 2019 Toyota 4Runner

Replacing a fuse in the 2019 Toyota 4Runner is a relatively straightforward process. Here’s a step-by-step guide:

Materials:

1. The new fuse of the correct amperage.
2. Fuse puller or needle-nose pliers.

Instructions:

1. Locate the Fuse Box: The fuse box in the 2019 Toyota 4Runner is typically located in the engine compartment.
2. Turn Off the Ignition: Before you start replacing fuses, ensure that the ignition is turned off to prevent any electrical mishaps.
3. Identify the Blown Fuse: Inspect the fuses to identify the one that needs to be replaced. A blown fuse will typically have a broken filament or a visibly burnt appearance.
4. Remove the Blown Fuse: Using a fuse puller tool or a pair of needle-nose pliers, carefully remove the blown fuse from its socket. Be gentle to avoid damaging the fuse box or surrounding components.
5. Insert the New Fuse: Take a new fuse of the same amperage rating as the one you removed. Align the new fuse with the socket and gently push it into place until it’s securely seated.
6. Test the Circuit: Once the new fuse is installed, turn on the ignition and test the circuit to ensure that the issue has been resolved. If the fuse blows again immediately, there may be an underlying electrical problem that needs to be addressed.
7. Close the Fuse Box: Once you’ve confirmed that the new fuse is working correctly, close the fuse box cover securely.
8. Dispose of the Old Fuse: Safely dispose of the old, blown fuse. If it’s a glass fuse, wrap it in paper or plastic before disposing of it to prevent injury.

Tips:
Always use a fuse with the correct amperage rating to prevent electrical issues or damage to the vehicle.
